Definitions

  • the present invention relates to a device and a method for controlling the discharge of logs from a rewinding machine.
  • rewinders are used for winding a predetermined amount of paper or other web material around a tubular core, usually made of cardboard, so as to produce paper reels, commonly called “logs”, having a predetermined diameter.
  • the winding of the web material on the core is made in a station provided with a pair of winding rollers by means of which the logs are retained and made to rotate about the longitudinal axis of the core until the logs reach the required diameter.
  • Rewinding machines of this type are described, for example, in U.S. 2003/0001042 A1, U.S. Pat. No. 6,565,033 and WO 01/64563.
  • the log must leave the rewinder to be led to other processing steps.
  • the log is released from the winding rollers and is thus free to roll along an outlet or discharge plane.
  • the main purpose of the present invention is to propose a device to effectively control the discharge of the logs while avoiding the damage of the same.
  • the advantages deriving from the present invention consist essentially in that it is possible to control very effectively the speed of discharge or exit of the logs from the rewinder; that it is possible to preserve the integrity of the logs thus controlled; that an apparatus according to the invention is simple, cheap and reliable even after a prolonged period of operation.
  • FIG. 1 schematically represents a rewinding machine provided with a control device in accordance with the invention
  • FIGS. 2-6 schematically represent a device according to the invention in different operating phases
  • FIG. 7 represents a particular of FIG. 3 with parts omitted to better illustrate others;
  • FIG. 8 schematically represents a further embodiment of a device according to the invention.
  • FIG. 1 schematically shows, only to allow identification of the position of the device object of the invention, the following components of a rewinding machine:
  • the web ( 4 ) may consist of a single ply or more superimposed plies.
  • a device for controlling the discharging or output speed of the logs ( 3 ) coming out of a rewinding machine comprises a rotatable body ( 6 ) arranged above the said plane ( 5 ) downstream of said winding rollers (A 1 , A 2 ), with axis (a) parallel to the axis of the latter, that is, with axis parallel to that of the logs ( 3 ) exiting from the rewinding machine.
  • said axis (a) is horizontal and parallel to the plane ( 5 ) along which roll the logs formed in the station (FL), i.e., is orthogonal to the direction (F) of the logs ( 3 ) leaving the station (FL).
  • Said body ( 6 ) is controlled by a corresponding electric motor (not shown) which controls its rotation with a predetermined angular speed about the respective longitudinal axis.
  • said body ( 6 ) intended to slow down the motion of the log ( 3 ) downstream of station (FL), is a body that picks up the log ( 3 ) on the plane ( 5 ), dissipates its kinetic energy and places it on an extension ( 50 ) of the same plane ( 5 ) downstream of the pickup point ( 51 ) that is on the trailing edge of the plane ( 5 ).
  • the body ( 6 ) has a lateral concave surface ( 62 ), with the concavity facing inwards, which in the example illustrated in FIGS. 2-6 , is a portion of cylindrical surface whose cross section has the shape of a circular arc of angular amplitude (Q) greater than 180° and preferably between 180° and 270°.
  • Q angular amplitude
  • FIGS. 2-6 represent a sequence of positions assumed by the body ( 6 ) during the operation of the present device: in a first phase ( FIG. 2 ), the log ( 3 ), the formation of which has just ended, is freed from the roller (A 1 ) as indicated by arrow “RA” and therefore it rolls on the plane ( 5 ) and enters into the concavity of the body ( 6 ), as indicated by arrow “F”, suitably positioned with its front edge ( 60 ) at the point ( 51 ) where the logs are taken. Subsequently ( FIGS.
  • the log ( 3 ) is substantially stationary relative to the plane ( 50 ).
  • the log ( 3 ) drawn with dashed lines is at the time in which it is released from the body ( 6 ) and the arrow “E” indicates the exit of the log ( 3 ) from the latter.
  • the body ( 6 ) is in a position identical to that of FIG. 2 , that is, ready to receive another log.
  • the location of the log ( 3 ) inside the body ( 6 ) is substantially fixed with respect to the discharge plane ( 5 , 50 ).
  • the log ( 3 ) rolls freely on the inner wall of its lateral surface ( 62 ) and remains substantially above the aforesaid pickup point ( 51 ).
  • the direction of rotation (G) of the body ( 6 ) is such that its front edge ( 60 ), when it is in correspondence of the pickup point ( 51 ), moves in the direction opposite to the direction (F) from which the logs ( 3 ) come. Moreover, the body ( 6 ) is positioned with respect to the plane ( 5 ) in such a way that its front edge ( 60 ) is substantially at the same height of the pickup point ( 51 ) in the phase in which a log ( 3 ) exiting from the station (FL) has to be taken.
  • the body ( 6 ) rotating in a direction (G) opposite to the direction (F) from which from the logs ( 3 ) arrive, receives the latter and houses them temporarily in the pocket (P) delimited by the inner wall of its lateral surface ( 62 ), allowing the same logs to roll freely inside of said pocket, without translating, for all the time required by the completion of a turn of the body ( 6 ) around the axis (a).
  • the body ( 6 ) has a single pocket (P) for accommodating the logs ( 3 ).
  • the body ( 6 ) has a plurality of pockets (P) each adapted to receive a log ( 3 ) coming from the station (FL). Also in this example, the body ( 6 ) rotates around an axis (a) parallel to the logs ( 3 ) in a direction (G) opposite to that (F) of origin of the same logs.
  • the operation is completely analogous to that described above, with the difference that in this case the body ( 6 ) carries more logs ( 3 ) at the same time instead of only one log, and that during transport operated by the body ( 6 ), the logs ( 3 ) do not remain constantly above of the pickup point. Owing to the greater transverse extension of the body ( 6 ), the latter is disposed between the planes ( 5 ) and ( 50 ) that in this case are not adjacent but separated from each other by the body ( 6 ).
  • the surface of the logs ( 3 ) will not be damaged even if their speed is reduced as desired.
  • the rotation of the body ( 6 ) is properly synchronized with the production of the logs in the station (FL).
  • a method o in accordance with the present invention involves the production of logs ( 3 ) formed by a roll obtained from a web of paper material in a corresponding station (FL) of a rewinding machine, the discharge of the logs ( 3 ) from said station (FL) along a predetermined discharge direction (F), and the collection of logs ( 3 ) in a predetermined pickup point ( 51 ) with a container body ( 6 ) that at said pickup point ( 51 ) moves along a direction (G) opposite to said discharge direction (F) of the logs ( 3 ).
